crunchbang

This is the most accessible way to experiment with Openbox.
See a nice review here

But a much nicer way is to follow this guide by Urukrama

Working with Openbox is addictive because of its simpleness, very productive because of keybindings and dmenu. Other good points are its ease of configuration, its wonderful looks, its fastness, low system requirements.
It's the complete opposite fo Winows Vista where everything is bloated and overdone with unnecessary complicated menu's.
On a well configured Openbox system the learning curve for pc newbies will be much and much lower than on any other configuration I know.

This is the way to go for people in education working with older hardware and possibilities to deploy a specific software setup.

Another competitor in this field is SliTaz
The wonderful thing about SliTaz is that it is the ideal on-the-road distro with a Usbstick on which you can very easily put your home partition. A problem I found that it doesn't support a very high screen resolution.
A critical review here

Just try it and you'll never regret it.

wbar, very lightweight osx like dock for openbox


Wbar is a very nice lightweight dock for openbox.
To config via GUI install wbarconf

Here a screenshot; please also note the tint bar at the top; the conky listing of the openbox keybindings and the nice tranquility theme in the thunar window.

Skippy, task swithcher for openbox

What you do with alt+tab in Windows and most Linux distro's you can visualize with very large window thumbnails in a nice way with Skippy .
See here for a nice screenshot

when you 've lost admin rights

I couldn't access my cdrom drives and it had something to do with the user rights. A short while later I could access my drives but had lost admin rights!!

The quickest solution I found and tried was:
Reboot, when entering the grub menu press c to prevent further booting. Choose: Ubuntu recovery mode. Then you get a menu: choose work in terminal
and enter: usermod -a -G admin username

After that's done (without feedback) type reboot.
Other useful commands
To get info on your cdrom drives: dmesg | grep CD-ROM
b.t.w. the command that got me into trouble was:
first: usermod -G cdrom username
and then:
chmod 660 /dev/(name drive)
found with
ls -la / media
or
ls -la /dev/cdrom*

Change username into your own username.

Howto spot which ports are active

"I like to use netstat -ntulp that will show everything that is listening tcp and udp and the ip that it is listening on."

Making Keybindings in OpenBox more accessible with Conky

Open box is a wonderful clean window manager that is very low on resources when you start an openbox session. And if you use the wonderful Tranquility Open box theme computung starts to get really nice. (Don't miss the wonderful pine background).

The best place to start is Urukrama weblog that has a very clear and easy install guide for Open box and all kind of extra possiblities to enrich the OpenBox environment.
When I was asked to prepare a pc for a 12 year old child on a old 500 mhz Pentium my thoughts immediately were about how to make the OpenBox environment easy and super user-friendly.
In the Crunchbang distro. that I didn't want to use I saw how conky was used as a reminder for keybindings for starting programs. In openBox keybindings are very easily set in the rc.xml file in ./config/openbox. There is a gui program that is to be used when setting a theme for instance, Obconfig, a fine program but without the possibility to set keybindings. The basics are explained here.
Urukrama gives some suggestions for using keybindings to start programs. Here is what I have defined as keybindings.



And here is the .conkyrc file that comes with it and is palced in the ./home folder:


# conky configuration
#
# The list of variables has been removed from this file in favour
# of keeping the documentation more maintainable.
# Check http://conky.sf.net for an up-to-date-list.

# For ideas about how to modify conky, please see:

# For help with conky, please see:
